This webinar will introduce Sentinel-5p data, especially Level 2 Products. It will discuss the structure of the netCDF files in which the data is distributed and explore them using a well-known Python library (xarray). In addition, the webinar will show how to generate Level 3 products using HARP for a multi-temporal evaluation of NO2 over …
A sudden stratospheric warming (SSW) is a large-scale meteorological phenomenon in the winter stratosphere, which involves a rapid rise in the polar temperature by a few tens of kelvins in several days. SSWs are triggered by an injection of stationary planetary waves from the troposphere. These events are rare in the Southern Hemisphere, therefore they …
Some of the strongest lightning discharges occurring at the Earth surface generate short electromagnetic signals that can propagate at very large distances both at the surface of the planet and in space. During a lightning discharge, the whole electromagnetic spectrum is excited, from radio frequencies to the visible and beyond. The conditions of the atmosphere …
Volcanic monItoring using SenTinel sensors by an integrated Approach (VISTA) project is aimed at developing a novel ensemble of algorithms to completely characterized the effects of volcanic emissions on land and atmosphere. Volcanic activity is observed worldwide with a variety of remote sensing instruments, each one with advantages and drawbacks. Because a single remote sensing …
South America is a rapidly developing continent of planetary importance. It hosts the Amazon forest, which is the single largest source of biogenic volatile organic compound (BVOC) emissions into the global atmosphere; it is also a region where extremely violent and extensive wildfires are known to cause widespread damages and fatalities. In addition, the degradation …
TOP is a web-based platform offering users from the atmospheric sciences domain a Virtual Research Environment (VRE) to exploit Copernicus atmospheric and climate data products, such as COPERNICUS Sentinel-5 Precursor data and CAMS products. Deployed on the MUNDI DIAS, it is the first operational platform implementing the data triangle (EO, model and in-situ data) and …
A new dataset of vertical column densities of H2O and HDO retrieved from short-wave infrared reflectance measurements by the TROPOMI instrument onboard the Sentinel-5p satellite was recently released. The data quality shows improvements in noise level compared to previous missions like SCIAMACHY. The retrieval methodology, the validation approach and demonstrative applications of the dataset are …
The capability of Sentinel-5p for aerosol monitoring is currently not used to its full potential. However, satellite observations in the spectral range from approximately 340 to 400 nm are known to have unique sensitivity to elevation and absorption of tropospheric aerosols. Traditionally, this sensitivity is used in many ozone monitoring instruments such as TOMS, GOME-1, …
The course will introduce learners to the role of satellite ‘Earth observation’ (EO) technology in monitoring the Earth’s Atmosphere and the data it produces looking also at the importance of ground based remote sensing and in situ observations, which complements as well as validates EO data. During the first week state of art atmospheric scientists …
Currently we speak of the ‘golden age’ of Earth Observation (EO). Not only can we access a variety of data from heritage and current EO missions serving scientific and operational needs, new systems for monitoring our blue planet are constantly being planned, built, and sent into the Earth orbit. Regarding atmospheric science, a major step …
